Can onsemi’s GaNEXUS Power Portfolio Accelerate Its AI Data Center Growth Story?
onsemi has introduced GaNEXUS, a new gallium nitride power portfolio aimed at fast-growing markets such as AI data centers, industrial automation, robotics, electric vehicle charging, and energy infrastructure. The move comes as artificial intelligence workloads are pushing data centers to demand more efficient, compact, and thermally stable power systems.
According to onsemi’s announcement, the GaNEXUS portfolio includes GaN FETs across voltage ranges from 40V to 650V, along with 650V GaNEXUS Smart devices that include integrated protection features. These products are currently sampling and are designed to deliver faster switching speeds, lower switching losses, higher power density, and improved thermal performance compared with traditional silicon-based solutions.
Why GaNEXUS Matters for AI Data Centers
AI data centers are becoming one of the most power-hungry parts of the technology economy. Advanced GPUs, accelerators, servers, and networking systems require large amounts of electricity, and that creates pressure on power conversion systems. In simple terms, data centers need to move electricity from the grid to chips with less wasted energy, less heat, and smaller hardware.
This is where gallium nitride, or GaN, becomes important. GaN power devices can switch faster and operate more efficiently than many silicon-based components. EPC describes GaN as offering higher breakdown strength, faster switching speed, higher thermal conductivity, and lower resistance than silicon-based devices.
For AI infrastructure, these qualities matter because power loss becomes costly at scale. Even small efficiency improvements can reduce heat, cooling needs, equipment size, and electricity costs across thousands of servers. That gives onsemi a potential opening to position GaNEXUS as a key technology for next-generation AI power delivery.
onsemi’s Strategy: More Than Just Chips
onsemi is not only selling standalone GaN devices. The company says GaNEXUS can be combined with its Treo Platform, which supports integrated sensing, control, protection, and power management. This broader system approach may help customers simplify design work and improve reliability in demanding applications.
That matters because data center operators and power-system designers do not only want faster parts. They want complete solutions that reduce complexity, support uptime, and lower total system cost. If GaNEXUS can help shrink power systems, reduce cooling requirements, and improve responsiveness, it could strengthen onsemi’s role in the AI infrastructure supply chain.
The AI Data Center Opportunity Is Expanding Fast
The timing is important. AI is driving a major buildout of data center infrastructure worldwide. McKinsey estimates that global data center spending could reach $7 trillion by 2030, showing how large the infrastructure opportunity may become.
At the same time, the International Energy Agency has warned that affordable, reliable, and sustainable electricity will be a major factor in AI development because training and running AI models takes place in large, power-intensive data centers.
This creates a clear market need: AI data centers must keep growing, but they also need better power efficiency. onsemi’s GaNEXUS portfolio directly targets that problem.
Potential Benefits for onsemi
If adoption grows, GaNEXUS could help onsemi in several ways. First, it may give the company stronger exposure to AI infrastructure, one of the most watched growth themes in semiconductors. Second, it could expand onsemi’s power-management portfolio beyond traditional silicon technologies. Third, it may help the company compete in higher-value applications where efficiency, thermal performance, and reliability are critical.
Investors are also watching onsemi closely. As of June 10, 2026, ON shares were trading at about $109.44, with a market capitalization of roughly $43.13 billion.
Risks and Challenges
Still, GaNEXUS is not a guaranteed growth engine. The portfolio is currently sampling, so meaningful revenue contribution may take time. Customers must test, qualify, and integrate the products into their systems before large-scale orders can appear. Competition is also intense, with several semiconductor companies pursuing GaN, silicon carbide, and advanced power-management solutions for AI infrastructure.
Another challenge is that AI data center demand can be uneven. Spending depends on hyperscaler budgets, energy availability, server demand, and the pace of AI adoption. If the market slows or customers delay infrastructure projects, growth may take longer than expected.
Final Takeaway
GaNEXUS gives onsemi a timely product story in one of the strongest semiconductor growth markets: AI data centers. The portfolio’s focus on faster switching, lower losses, higher power density, and better thermal performance matches the needs of modern AI infrastructure.
While it is too early to say how much revenue GaNEXUS will generate, the launch strengthens onsemi’s position in advanced power electronics. If AI data center investment continues to rise and customers adopt GaN-based power systems at scale, GaNEXUS could become an important part of onsemi’s long-term growth story.
